Kuniharu often wears a suit and tie when going to work. He sports a pair of glasses and has brown hair and eyes, a change from his first appearance in the one-shot volume of the series where he has black hair and eyes.[1]


He is sloppy and slovenly, often begging with disgusting teary faces towards his son. He is a layman who is often seen licking the shoes of his boss. He works as a manga editor. His special skill is flattering his boss. His father (paternal grandfather of Kusuo and Kusuke) has passed away while his mother (paternal grandmother of Kusuo and Kusuke) lives in a family house.

  • He mentions that his mother is still alive while his father is deceased.[4]
  • During one of his lover's quarrel with Kurumi, it resulted in Kusuo finding out that both have the same level of love for each other with a result of 38,689 in Kusuo's affection meter.[5]
